10070001URF5
ISE unit result error:
Urine cycle error. No
flow
Calibrator A and B bottle
empty; wrong electrode
installation
Replace the calibrator A and B, then recalibrate; check
the installation of the electrodes.
10070001URS5
ISE unit result error:
Urine cycle error. Air in
sample
Insufficient sample volume Rerun after refilling.
100700020025
ISE unit result error: Na
electrode voltage
overflow (Cal B/Sample)
Electrodes performance
degrading.
Replace the electrodes and or
calibrator A
Run test after replacing problematic electrodes;
Check the calibrator A and recalibrate; there might be
drift, if it is a new electrode. Rerun after 15 minutes.

overflow (Cal B/Sample)
Electrodes performance
degrading.
Replace the electrodes and or
calibrator A
Run test after replacing problematic electrodes;
Check the calibrator A and recalibrate; there might be
drift, if it is a new electrode. Rerun after 15 minutes.
